ABSTRACT:
A conventional leaf spring suspension system as applicable to pick-up trucks, vans and motor homes produces a harsh ride and is unable to compensate for changes in vehicle ride height and quality brought about by uneven or heavy vehilcle loading conditions. A more effective suspension is achieved by incorporating air springs to compliment the existing leaf springs thus providing the ability to adjust ride height and hence, ride quality. This is accomplished by replacement of existing suspension components, such as shock absorbers, with, on the front suspension, an air spring and various attachment brackets and, on the rear, an air spring in combination with a sub-frame and torque arm linked cross beam, carried between which is a low pressure air spring.
